I used to do that too when I was a kid every time we would go swimming. Good thing it was effective in your case. Sa kin hindi. Suki ako ng ENT even then until now. Btw, nagswimming ka ba kaya natrap tubig sa tenga mo? Or naaliw ka sa shower? Hehe, hinay-hinay lang. Mahirap mabingi. Parang matanda!
